NASA’s renowned Mars rover Opportunity has been spied anew in a fabulous new photo captured just days ago by NASA’s ‘Spy in the Sky’ orbiter circling overhead the Red Planet. See Opportunity from above and below – from today’s location. See orbital view above – just released today.

The highly detailed image was freshly taken on Feb. 14 (Valentine’s Day 2014) by the telescopic High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO) as the decade old Opportunity was investigating the tasty alien terrain on ‘Murray Ridge’ – nearby the celebrated ‘jelly doughnut’ rock by the summit of Solander Point. See surface views below.

The fabulous orbital image shows not only rover Opportunity at her location today, but also the breathtaking landscape around the robots current location as well as some of the wheel tracks created by the Martian mountaineer as she climbed from the plains below up to near the peak of Solander Point.

The scene is narrowly focused on a spot barely one-quarter mile (400 meters) wide.

Murray Ridge and Solander Point lie at the western rim of a vast crater named Endeavour that spans some 22 kilometers (14 miles) in diameter.

Here is the corresponding Martian surface view snapped by Opportunity on Feb. 16, 2014 (looking back and down to Endeavour crater), while she’s being imaged from Mars orbit on Feb. 14, 2014:

Endeavour is an impact scar created billions of years ago. See our 10 Year Opportunity traverse map below.

And believe it or not, that infamous ‘jelly doughnut’ rock was actually the impetus for this new imaging campaign by NASA’s MRO Martian ‘Spysat.’

To help solve the mystery of the origin of the shiny 1.5 inches wide (4 centimeters) ‘jelly doughnut’ rock, dubbed ‘Pinnacle Island’, the science team decided to enlist the unparalleled capabilities of the HiRISE camera and imaging team in pursuit of answers.

‘Pinnacle Island’ had suddenly appeared out of nowhere in a set of before/after pictures taken by Opportunity’s cameras on Jan, 8, 2014 (Sol 3540), whereas that exact same spot had been vacant of debris in photos taken barely 4 days earlier. And the rover hadn’t budged a single millimeter.

So the HiRISE research team was called in to plan a new high resolution observation of the ‘Murray Ridge’ area and gather clues about the rocky riddle.

The purpose was to “check the remote possibility that a fresh impact by an object from space might have excavated a crater near Opportunity and thrown this rock to its new location”- now known as Pinnacle Island, said NASA in a statement.

Well, no fresh crater impacting site was found in the new image.

“We see no obvious signs of a very recent crater in our image, but a careful comparison to prior images might reveal subtle changes,” wrote HiRISE principal investigator Alfred McEwen in a description today.

Back on sol 3365 we took this image of Solander Point as we approached it. Here I have plotted the subsequent route that Opportunity has taken in climbing up the ridge. The outcrop shown I the images below are near the end of the yellow traverse line. Caption and mosaic by Larry Crumpler/NASA/JPL/

In the meantime, as I reported here a few days ago the mystery was solved at last by the rover team after Opportunity drove a short distance away from the ‘jelly doughnut’ rock and snapped some ‘look back’ photographs to document the ‘mysterious scene’ for further scrutiny.

It turns out that the six wheeled Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing and breaking it apart with the force from the wheels and her hefty 400 pound (185 kg) mass.

“Once we moved Opportunity a short distance, after inspecting Pinnacle Island, we could see directly uphill an overturned rock that has the same unusual appearance,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a NASA statement.

“Murray Ridge” and the Solander Point mountaintop are of great scientific interest because the region is riven with outcrops of minerals, including clay minerals, that likely formed in flowing liquid neutral water conducive to life – potentially a scientific goldmine.

Today, Feb 19, marks Opportunity’s 3582nd Sol or Martian Day roving Mars. She is healthy with plenty of power.

So far she has snapped over 188,800 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.07 miles (38.73 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Read more about sister Spirit – here and here.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and just crested over the Dingo Gap sand dune. She celebrated 500 Sols on Mars on New Years Day 2014.

And a pair of new orbiters are streaking to the Red Planet to fortify Earth’s invasion fleet- NASA’s MAVEN and India’s MOM.

Finally, China’s Yutu rover has awoken for her 3rd workday on the Moon.

Stay tuned here for Ken’s continuing Opportunity, Curiosity, Chang’e-3, LADEE, MAVEN, Mars rover, MOM and continuing planetary and human spaceflight news.

Gaping Inside The Huge Vehicle Assembly Building NASA Used For Space Shuttles And Moon Missions

ORLANDO, FLORIDA – There’s something about this city that brings out the crazy travel planner in me. I visited here four times betting a shuttle would launch, luckily winning on three occasions. I also once took an epic bus trip from here as far south as Fort Lauderdale before zooming back north, looking at space exhibits up and down the coast.

This time, it was to catch the Vehicle Assembly Building tour before it was gone. Tours inside the iconic, huge structure — best known as the spot where the Apollo rockets and space shuttle went through final assembly before going to the pad — are closing down on Sunday (Feb. 23). Warned by Ken Kremer and others that soon the public couldn’t get inside, I booked a ticket late last month after the announcement was made.

I came in search of the past, but what I saw instead was the future — an agency preparing to hand over a launch pad to SpaceX, and at least part of an Orion spacecraft on the VAB floor, ready to be shipped to Langley, Virginia.

It’s hard to convey the size of one of the world’s largest buildings. It’s so big that it can form its own weather inside, without proper air conditioning. It stands almost twice as high as the Statue of Liberty, at 160 meters (525 feet) tall and 158 meters (518 feet) wide.

The 3.25-hectare (8-acre) building needed to be so huge to hold the 363-foot (111-meter) Apollo/Saturn vehicles in the 1960s and 1970s, and then was modified for use of the shuttle in the 1970s until just a few years ago.

What surprised me, however, was how narrow the main floor appeared. That’s because there are all of these catwalks on either side of the space for workers to get access to different parts of the spacecraft.

Tours of this building were off-limits between 1978 and 2011, when the shuttle program was launching its vehicles in earnest. After the program retired, however, NASA opened the VAB and nearby facilities (including the Launch Control Center and Launch Pad 39A) up to visitors. As these areas are now being used by contractors and the Orion/Space Launch System, however, the agency is closing down public access so the work of getting to space can continue.

As NASA prepares for a test of Orion later in 2014, the agency is also looking to lease out parts of the big building to commercial vendors. It appears negotiations for at least some of the high bays are ongoing.

Meanwhile, we were lucky enough to glimpse at least part of an Orion spacecraft prototype ready for shipping to Langley, Virginia, with about a dozen people busily milling around it as it lay on the back of a tractor trailer. It’s unclear to me how much of the spacecraft was inside that package, but our tour guide told us it was the whole thing. Yes, the truck looked really tiny in the big building.

Our group also had the chance to visit Launch Pad 39A, one of the two pads used in the Apollo program and also for shuttle. It was eerie to see the pad still in its shuttle configuration, complete with the clamshell-like structure that used to protect the vehicle from the weather until just prior to launch.

All that is going to be torn down for scrap shortly as SpaceX likely takes over the pad, our guide told us, and it’s unclear how long pad tours will continue. Likely those will be gone soon as well. Meanwhile, I took special delight standing in the “flame trench” where noxious chemicals from the launch used to flow. You certainly didn’t want to be close to this spot when a Saturn V or shuttle stack took off.

By the way, the first thing I thought of when I saw the huge pipes on the side of the picture below is the 1996 movie Apollo 13, which has a dramatic launch sequence that includes a neat pan across the coolant tubing. That’s about the time when I decided I wanted to see the VAB and launch pads, so it only took me 18 years to get out here.

Although these tours are likely changing or closing, these steps are to get the complex ready for manned launches again, if the current plan and funding holds as NASA hopes.

In the meantime, there are other things to see at the center. The picture at the top of this article shows the Vehicle Assembly Building just before the launch of STS-129, my first experience seeing a shuttle rocket into space.

That shuttle happened to be Atlantis, which today is handily displayed nearby in the KSC Visitor Complex. Weird, I thought, as I looked at the immense vehicle’s bulk. The last time I saw you in November 2009, you were on your way to orbit and making a lot of noise.

I wonder how much things will change at KSC in the next four years.

Private Cygnus Cargo Carrier departs Space Station Complex

The Cygnus private cargo craft built by Orbital Sciences Corp. was released from the station's robotic arm at 6:41am EST, Feb 18. It will burn up in Earth's atmosphere on Wednesday, Feb. 19, 2014. Credit: NASA TV

Following a picture perfect blastoff from NASA’s frigid Virginia spaceport and a flawless docking at the International Space Station (ISS) in mid-January, the privately built Cygnus cargo resupply vehicle has completed its five week long and initial operational station delivery mission and departed the facility early this morning, Tuesday, Feb. 18.

The Expedition 38 crewmembers Michael Hopkins of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) demated the Orbital Sciences Cygnus commercial spacecraft from the Earth-facing port of the Harmony node using the Canadian built robotic arm at about 5:15 a.m. EST.

The cylindrically shaped ship was released from the grappling snare on the terminus of the 57 foot long extended arm at about 6:41 a.m. EST and with a slight shove as both vehicles were flying at 17500 mph and some 260 miles (415 km) altitude above Earth over the southern tip of Argentina and the South Atlantic Ocean.

The astronauts were working at a robotics work station in the windowed Cupola module facing the Earth. The arm was quickly pulled back about 5 feet (1.5 m) after triggering the release from the grappling pin.

NASA TV carried the operation live. Station and arm cameras provided spectacular video views of the distinctive grey cylindrical Cygnus back dropped by the massive, cloud covered blue Earth as it was released and sped away.

Cygnus was commanded to fire its jets for the departure maneuvers to quickly retreat away from the station. It was barely a speck only 5 minutes after the arm release maneuver by Wakata and Hopkins.

“The departure was nominal,” said Houston mission control. “Cygnus is on its way.”

The solar powered Cygnus is America’s newest commercial space freighter and was built by Orbital Sciences Corporation with seed money from NASA in a public-private partnership aimed at restoring the cargo up mass capabilities lost following the retirement of NASA’s space shuttles in 2011.

Cygnus, as well as the SpaceX Dragon cargo vessel, functions as an absolutely indispensable “lifeline” to keep the massive orbiting outpost alive and humming with the science for which it was designed.

The freighter delivered a treasure trove of 1.5 tons of vital research experiments, crew provisions, two dozen student science projects, belated Christmas presents, fresh fruit and more to the million pound orbiting lab complex and its six man crew.

The milestone flight dubbed Orbital 1, or Orb-1, began with the flawless Jan. 9 blast off of Cygnus mounted atop Orbital Sciences’ two stage, private Antares booster on the maiden operational launch from NASA’s Wallops Flight Facility along Virginia’s eastern shore. See a gallery of launch photos and videos – here and here.

“Today’s launch gives us the cargo capability to keep the station going,” said Frank Culbertson, executive vice president and general manager of Orbital’s advanced spaceflight programs group, and former Space Shuttle astronaut.

And NASA’s commercial cargo initiative is even more important following the recent extension of station operations to at least 2024.

“I think it’s fantastic that the Administration has committed to extending the station,” Culbertson told me following the launch at NASA Wallops.

“So extending it gives not only commercial companies but also researchers the idea that Yes I can do long term research on the station because it will be there for another 10 years. And I can get some significant data.”

Following a two day orbital chase the Cygnus spacecraft reached the station on Jan. 12.

The ship is named in honor of NASA shuttle astronaut C. Gordon Fullerton who passed away in 2013.

Science experiments weighing 1000 pounds accounted for nearly 1/3 of the cargo load.

Among those were 23 student designed experiments representing over 8700 K-12 students involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.

The students are participants of the Student SpaceFlight Experiments Program (SSEP) sponsored by the National Center for Earth and Space Science Education (NCESSE).

Over 20 of the students attended the launch at Wallops. The student experiments selected are from 6 middle school and high school teams from Washington, DC, Traverse, MI, Downingtown and Jamestown, PA, North Charleston, SC and Hays County, TX.

Student Space Flight teams at NASA Wallops Science experiments from these students representing six schools across America were selected to fly aboard the Cygnus spacecraft which launched to the ISS from NASA Wallops, VA, on Jan . 9, 2014, as part of the Student Spaceflight Experiments Program (SSEP).

“More than half the student experiments were activated within four days of arrival,” Dr. Jeff Goldstein, Director of the NCESSE, told Universe Today exclusively.

Ant colonies from three US states were also on board to study “swarm behavior.” The “ants in space” experiment was among the first to be unloaded from Cygnus to insure they are well fed for their expedition on how they fare and adapt in zero gravity.

33 cubesats were also aboard. Several of those were deployed last week from the Japanese Experiment Module airlock.

The Orbital-1 mission was the first of 8 operational cargo logistics flights scheduled under Orbital Sciences’ multi-year $1.9 Billion Commercial Resupply Services contract (CRS) with NASA to deliver 20,000 kg (44,000 pounds) of cargo through 2016.

Cygnus was berthed at the ISS for some 37 days.

After fully unpacking the 2,780 pounds (1,261 kilograms) of supplies packed inside Cygnus, the crew reloaded it with all manner of no longer need trash and have sent it off to a fiery and destructive atmospheric reentry to burn up high over the Pacific Ocean on Feb. 19.

“The cargo ship is now a trash ship,” said NASA astronaut Cady Coleman.

“Getting rid of the trash frees up a lot of valuable and much needed space on the station.”

When it reaches a sufficiently safe separation distance from the ISS, mission controllers will fire its engines two times to slow the Cygnus and begin the final deorbit sequence starting at about 8:12 a.m. on Wednesday.

Cygnus departure is required to make way for the next private American cargo freighter – the SpaceX Dragon, which is now slated to blast off from Cape Canaveral, Florida on March 16 atop the company’s upgraded Falcon 9 booster.

Two additional Antares/Cygnus flights are slated for this year.

They are scheduled to lift off around May 1 and early October, said Culbertson.

Indeed there will be a flurry of visiting vehicles to the ISS throughout this year and beyond – creating a space traffic jam of sorts.

Stay tuned here for Ken’s continuing Orbital Sciences, SpaceX, commercial space, Orion, Chang’e-3, LADEE, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Savage Spacesuit: ‘Mythbusters’ Host’s Mercury Costume Looks Real Enough For Space

Mythbusters' Adam Savage shows off a Mercury replica spacesuit in February 2014. Credit: Tested/YouTube (screenshot)

Who wants Adam Savage’s job right now? The cohost of Mythbusters spent the last year working with a San Francisco Bay-area costume designer to come up with this remarkable Mercury spacesuit. While it’s not a faithful replica of any one mission — it’s more a blend of greatest hits from the designs of several — it really looks like Savage could step into a spacecraft at any moment.

“The whole point of the Mercury program … was to figure out how to safely get people into space and what would happen to them,” Savage says in a new video, which you can see below.

“So every single time they came down from a Mercury mission they [the astronauts] would talk to the engineers and spend weeks in meetings going ‘Okay, I couldn’t move my arm this way. I couldn’t hit this switch in this way. I couldn’t turn my head.”

As if that isn’t cool enough, Savage also is sporting an Apollo flight jacket replica that is advertised as being pretty darn close to the original. Check out Adam Savage’s Tested blog for amazing photos as well as a more complete video (for premium members.)

Mercury was the first American spaceflight program, and had six flights between 1961 and 1963. For more information about the Mercury spacesuit, check out this chapter from NASA book “This New Ocean: A History of Project Mercury“. You can also see a photo gallery of different Mercury suits.

Coincidentally, there’s a travelling exhibit on about the history of spacesuits, which Universe Today’s David Dickinson wrote about last week.

At ‘Star City’, This Is How Astronauts Learn About Soyuz Spacecraft

European astronaut Andreas Morgensen resting between parabolas on a "Vomit Comet"-like plane during training in 2010.

While the world is having a good time watching Olympic sports in Sochi, about a day’s drive north in Russia there are a bunch of astronauts using their evenings for a different purpose: reading an 18-inch high stack of Soyuz spacecraft textbooks.

“So let’s study all this real quick, let’s learn everything, we’ll learn everything we have to learn, and then let’s go to sim[ulation],” says European astronaut Thomas Pesquet in a new video from living quarters in training facility Star City, near Moscow.

“Okay, but I think it takes about a year,” answers fellow European astronaut Andreas Mogensen.

“Oh … so we better get started,” Pesquet says, handing gobs of books to his colleague.

Mogensen has his hands full in other ways as well as he shows us around Star City: there’s a new baby in his family, as you see at the beginning. We doubt he’s getting a lot of sleep right now, but this will certainly be a memorable time as he prepares to be the first Dane in space in 2015.

100 Days of MOM – India’s 1st Mars Mission Streaking to Red Planet Rendezvous

India’s maiden Mars explorer, the Mars Orbiter Mission or MOM, celebrated 100 days speeding through space this past week, racing outwards on its historic journey to the Red Planet.

After streaking through space for some ten and a half months, the 1,350 kilogram (2,980 pound) MOM probe will rendezvous with the Red Planet on September 24, 2014 – where she will study the atmosphere and sniff for signals of methane.

Feb. 12, 2014 marked ‘100 Days of MOM’ since the picture perfect blast off on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

A series of six subsequent orbit raising maneuvers ultimately culminated with the liquid fueled main engine firing on Dec. 1, 2013 for the Trans Mars Injection(TMI) maneuver that successfully placed MOM on a heliocentric elliptical trajectory to the Red Planet.

The TMI, affectionately dubbed ‘The mother of all slingshots’ finally provided the craft with sufficient thrust to achieve escape velocity and blast free of the Earth’s sphere of influence forever and begin her nearly yearlong momentous voyage to Mars.

The first of four in flight Trajectory Correction Maneuvers, TCM-1, was conducted by firing the 22 Newton Thrusters for a duration of 40.5 seconds on December 11, 2013. A trio of additional TCM firings are planned around April 2014, August 2014 and September 2014.

Trans Mars Injection (TMI), carried out on Dec 01, 2013 at 00:49 hrs (IST) has moved the spacecraft in the Mars Transfer Trajectory (MTT). With TMI the Earth orbiting phase of the spacecraft ended and the spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun. Credit: ISRO

MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s inaugural foray into interplanetary flight.

During the first 100 days, the probe has traveled about 190 million kilometers and has a little less than 500 million kilometers and 205 days to go during her journey of some 680 million kilometers (400 million miles) overall.

A health check on February 6, 2014 confirmed that the 15 kg (33 lb) science payload comprising five Indian built instruments was turned “ON” and is operating well.

MOM is currently some 16 million km distant from Earth and one way radio signals take approximately 55 seconds.

“The round trip time is almost 2 minutes for a communication signal to go to MOM and come back, about the same time mom takes to make noodles!” ISRO noted humorously in a Facebook mission posting.

“Keep going MOM!”

MOM's first Trajectory Correction Manoeuver in Baiju Raj's imagination. — MOM’s first Trajectory Correction Manoeuver in Baiju Raj’s imagination.

Following the ten month cruise through space the orbital insertion engine will fire for the do or die burn on September 24, 2014 placing MOM into an 377 km x 80,000 km elliptical orbit around Mars.

MOM is not alone in the frigid vacuum of space. She is joined by NASA’s MAVEN orbiter in pursuit of Mars.

MOM will reach Mars vicinity just two days after the arrival MAVEN on Sept. 22, 2014.

To date MAVEN has flown over 137 million miles (221 million km) of its total 442 million miles (712 million km) path to Mars.

If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

Together, MOM and MAVEN will fortify Earth’s invasion fleet at Mars. They join 3 current orbiters from NASA and ESA as well as NASA’s pair of sister surface rovers – Curiosity and Opportunity.

Although they were developed independently and have different suites of scientific instruments, the MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist told Universe Today.

“We have had some discussions with their science team, and there are some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

“At the point where we [MAVEN and MOM] are both in orbit collecting data we do plan to collaborate and work together with the data jointly,” Jakosky said.

Stay tuned here for Ken’s continuing MOM, Opportunity, Curiosity, Chang’e-3, LADEE, MAVEN, Mars rover and more planetary and human spaceflight news.

Mystery of the Martian ‘Jelly Doughnut’ Rock – Solved

The mystery of the world famous “Jelly Doughnut” rock on Mars has at last been solved by diligent mission scientists toiling away in dank research labs on Earth.

The “Jelly Doughnut” rock achieved worldwide fame, or better yet infamy, when it suddenly appeared out of nowhere in pictures taken by NASA’s renowned Red Planet rover Opportunity in January.

And the answer is – well it’s not heretofore undetected Martian beings or even rocks falling from the sky.

Rather its ‘Alien Space Invaders’ – in some sense at least.

And that ‘Alien Space Invader’ is from – Earth! And her name is – Opportunity!

Indeed sister rover Curiosity may have unwittingly pointed to the culprit and helped resolve the riddle when she snapped a brand new photo of Earth – home planet to Opportunity and Curiosity and all their makers! See the evidence for yourselves – lurking here!

It turns out that the six wheeled Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing it with the force from the wheels and her 400 pound (185 kg) mass.

Fragments were sent hurtling across the summit of the north facing Solander Point mountain top, where she is currently climbing up ‘Murray Ridge’ along the western rim of a vast crater named Endeavour that spans some 22 kilometers (14 miles) in diameter. See traverse map below.

One piece unwittingly rolled downhill.

That rock fragment – now dubbed ‘Pinnacle Island’ – suddenly appeared in pictures taken by Opportunity’s cameras on Jan, 8, 2014 (Sol 3540).

And that exact same spot had been vacant of debris in photos taken barely 4 days earlier – during which time the rover didn’t move a single millimeter.

Pinnacle Island measures only about 1.5 inches wide (4 centimeters) with a noticeable white rim and red center – hence its jelly doughnut nickname.

The Martian riddle was finally resolved when Opportunity roved a tiny stretch and took some look back photographs to document the ‘mysterious scene’ for further scrutiny.

“We drove over it. We can see the track. That’s where Pinnacle Island came from.”

New pictures showed another fragment of the rock – dubbed ‘Stuart Island’ – eerily similar in appearance to the ‘Pinnacle Island’ doughnut.

To gather some up-close clues before driving away, the rover deployed its robotic arm to investigate ‘Pinnacle Island’ with her microscopic imager and APXS mineral mapping spectrometer.

The results revealed high levels of the elements manganese and sulfur “suggesting these water-soluble ingredients were concentrated in the rock by the action of water,” says NASA.

“This may have happened just beneath the surface relatively recently,” Arvidson noted, “or it may have happened deeper below ground longer ago and then, by serendipity, erosion stripped away material above it and made it accessible to our wheels.”

The Solander Point mountaintop is riven with outcrops of minerals, including clay minerals, that likely formed in flowing liquid neutral water conducive to life – potentially a scientific goldmine.

Opportunity is NASA’s 1st ever ‘Decade Old’ living Mars rover.

She has been uncovering and solving Mars’ billion years old secrets for over 10 years now since landing back on January 24, 2004 on Meridiani Planum – although she was only expected to function a mere 90 days!

Today, Feb 15, marks Opportunity’s 3578th Sol or Martian Day roving Mars.

So far she has snapped over 188,700 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.07 miles (38.73 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

While NASA’s newest lunar probe was tracking the stars, it also captured the moon! This series of star tracker images shows Earth’s closest large neighbour from a close-up orbit. And as NASA explains, the primary purpose of these star-tracking images from the Lunar Atmosphere and Dust Environment Explorer (LADEE) was not the lunar pictures themselves.

How Would Earth Send Messages To A Starship — Or A Distant Civilization?

I have a new exercise routine where I watch Star Trek: The Next Generation most mornings of the week while doing my thing. Besides serving as awesome distraction, the episodes do get me thinking about how humans would talk to extraterrestrials. It likely wouldn’t be as easy as the show portrays to zoom across space to conduct diplomatic negotiations at the planet “Parliament”, for example, so interstellar communication would be a problem.

Luckily for non-engineers such as me, there are folks out there (on Earth, at least) that are examining the problem of talking between stars. David Messerschmitt, of the University of California at Berkeley, is one of those people. A new paper by him on Arxiv examines the issue. Note this is a preprint site and not a peer-reviewed journal, but all the same it provides an intriguing addition to how to communicate outside of Earth.

Messerschmitt explains that humans already communicate with probes that are a fair distance from Earth (say, Voyager 1 in interstellar space) at radio frequencies, and there is some usage now of laser/optical communications (namely between the Earth and the moon).

Across greater distances, however, you lose information, the interstellar medium gets in the way, and stars shift due to relative motion. Besides all that, at first you wouldn’t know how the other civilization designs its systems and you could therefore send a message that wouldn’t be picked up.

He further explains that starships and civilizations would have different communications requirements. Starship communication would be two-way and based on a similar design, so success comes by having high “uplink and downlink transmit times”. The more information, the better it would be for scientific observations and keeping down errors.

Civilization-to-civilization chats, however, would present headaches. As with all diplomatic negotiations, crafting suitable messages would take time. Then we’d have to send the message out repeatedly to make sure it is heard (which actually means that reliability is not as big of a problem.) Then the ISM would have to be contended with (something that pulsar astronomers and astrophysicists are already working on, he said).

In either case — talking to starships or other civilizations — one can assume there’d be a lot of energy involved, he added. “Starships are likely to be much closer than the nearest civilizations, but the cost of either a large transmit antenna or transmit energy is likely to be considerably greater for the starship than for a terrestrial-based transmitter,” he said, suggesting that a solution would be to minimize the energy delivered to the receiver. Other civilizations may have found more efficient ways to overcome this problem, he added.

You can read more details of the research on Arxiv, where Messerschmitt talks about Gaussian noise, channel coding and other parameters to keep in mind during communication.

Martian Spacecraft Busts A Move To Glimpse Possible Water Flows

Just a few days ago, we posted about possibly salty water flows on Mars. Of note, the NASA press release noted, moisture is likely more prevalent in the morning and the Mars Reconnaissance Orbiter does most observations in the afternoon, local time. That’s too bad, we thought. But wait! It turns out that NASA Mars Odyssey spacecraft is going to change its orbit to get a better look.

It’s going to take nearly two years for NASA to maneuver the long-running Odyssey to the right spot, but at that point mission managers expect the spacecraft still has another decade of observations ahead of it based on current fuel consumption. That’s great considering that the spacecraft has been beaming back images since 2001!

Odyssey will be the first spacecraft to do dedicated morning observations of the planet since any NASA orbiter of the 1970s, which dates observations back to the Viking era (except for a few glimpses by European Space Agency spacecraft and previous NASA orbiters). Advances in imaging mean we will get a far clearer view of the ground than ever before.

“The change will enable observation of changing ground temperatures after sunrise and after sunset in thousands of places on Mars,” NASA stated. “Those observations could yield insight about the composition of the ground and about temperature-driven processes, such as warm-season flows observed on some slopes, and geysers fed by spring thawing of carbon-dioxide ice near Mars’ poles.”

The first maneuver took place Tuesday (Feb. 11) when a brief firing of Odyssey’s engines got the spacecraft pushing faster for an orbital shift. It will drift in that direction until November 2015, when controllers will do another maneuver to keep it in a stable location.

Right now, Odyssey is in a near-polar orbit that keeps local daylight at the same time below it. There have been a few changes to the timing over its dozen years of operation:

First six years (approx. 2001-2007): The orbit was mostly at 5 p.m. local solar time (as it flew north to south) and 5 a.m. local solar time on the south-to-north orbit. “That orbit provided an advantage for the orbiter’s Gamma Ray Spectrometer to have its cooling equipment pointed away from the sun,” NASA stated. At that time, the spectrometer found evidence of water ice, through the spectrum of hydrogen.
Next five years (approx. 2007-2012): The orbit shifted to 4 p.m. local solar time on north-to-south, and 4 a.m. south to north. While this allowed the Thermal Emission Imaging System to examine warm ground that made the mineral signatures in infrared pop out more easily, on the flip side of the planet Odyssey’s power system was under more strain because the solar panels couldn’t work as well in predawn light. Odyssey remained in that orbit until about the 2012 landing of the Curiosity rover, then was sent on a maneuver to move its orbit to later in the day to keep the battery functioning.
What’s next: Once Odyssey is in the right spot, the spacecraft will flip its daylight observations to scan the ground at 6:45 a.m. on the south-to-north part of the orbit. The spacecraft was in fact going in that direction already, but the new maneuver gets it there a bit sooner.

“We don’t know exactly what we’re going to find when we get to an orbit where we see the morning just after sunrise,” stated Philip Christensen of Arizona State University, who is THEMIS principal investigator and the person who suggested the move. “We can look for seasonal differences. Are fogs more common in winter or spring? We will look systematically. We will observe clouds in visible light and check the temperature of the ground in infrared.”

“We know that in places, carbon dioxide frost forms overnight,” he added. “And then it sublimates immediately after sunrise. What would this process look like in action? How would it behave? We’ve never observed this kind of phenomenon directly.”
